PROBLEM TO BE SOLVED: To provide an antifog and antifouling agent for organic substrate, capable of providing an inorganic cured coating having excellent antifouling and antifogging performances in addition to high hydrophilicity, hardness, adhesive strength to an organic substrate, and water resistance, and a method for coating an organic substrate with the antifog and antifouling agent.SOLUTION: An antifog and antifouling agent for organic substrate contains: 20-80 wt.% of methanol and/or ethanol; 20-80 wt.% of isopropyl alcohol, normal propyl alcohol or glycol ether; 1.0-70.0 wt.% of organosilica sol; 0.1-3.0 wt.% of tetrahydrofuran; and 0.02-0.4 wt.% of boric acid. The antifog and antifouling agent is brought into contact with a surface of an organic substrate followed by drying at ordinary temperature, whereby a coating is formed. |
